Abstract
Aim: The aim of the present work is to evaluate the value of magnetic resonance imaging (MRI) in assessment of Mullerian duct anomalies.
Patients and Methods: The study was performed on 20 female patients having clinical gynecological complains and US imaging findings suggestive of having mullerian duct anomalies. All of them undergone clinical assessment, pelvic ultrasound, hysterosalpingography and non-contrast MRI of the pelvis.
Results: The study included 4 uterine agenesis, 2 uterine hypoplasia, 2 bicornuate uteri, 2 unicornuate uteri, 4 septate uteri, 4 uterine didelphys (associated with hemivaginal septum), 1 arcuate uterus and 1 with isolated complete vaginal septum. The circumstances leading to the diagnosis were 1ry amenorrhea (25%), 1ry infertility (15%), dysmenorrhea (15%), recurrent abortion (15%), menstrual irregularity (10%), cyclic pelvic pain (5%) while 15 % were incidentally noted. US was done for all cases. It correctly diagnosed absent uterus in 4 cases with uterine agenesis and bicornuate uterus (in 2 cases). it incorrectly diagnosed the cases of uterine didelphys (4 cases) as bicornuate uterus. It missed the diagnosis of uterine hypoplasia, unicornuate uterus, septate uterus, arcuate uterus and vaginal septum. HSG was done for 10 cases. It correctly diagnosed a patient with unicornuate, 2 patients with bicornuate uterus & patient with arcuate uterus. It misdiagnosed the cases of uterine didelphys as unicornuate uterus and the cases of septate uterus as bicornuate uterus. MRI was done for all cases. It succeeded to identify all patients with MDAs with proper specification of its types showing100% diagnostic accuracy.
Conclusion: Hystrosalpingography proved to be not suitable for complete assessment of MDAs. It couldn’t be done to females with vaginal agenesis, vaginal septum and in patients with genital infection. Ultrasonography has limited capability in detection of double uterus, and cervical and vaginal anomalies. Not only MRI is sensitive in diagnosis of MDAs but also very accurate in MDAs specification. MRI is capable of detecting associated renal system anomalies.
